Method and system for determining the number of computing resources for executing a plurality of jobs. In accordance with the method and the system, the plurality of jobs along with a plurality of variables associated to the plurality of jobs may be received. The plurality of variables may include a mean processing time (μ), a standard deviation (σ), a service level agreement (α), and a confidence level (1-α). After the receipt of the plurality of variables, an inverse parameter (γ) may be determined using the mean processing time (μ), the standard deviation (σ), and the confidence level (1-α). Further, a queue length (k) may be computed based upon the total processing time (T), the mean processing time (μ), the standard deviation (σ), and the inverse parameter (γ). Finally, the queue length (k) and the number of jobs (n) may be processed in order to determine the number of computing resources.
